mass deployment using DHCP without need to reconfig int
Hello, I know there are lots of neat tools and solutions out there to manage this type of thing, but the reality is we only need a very simple solution and I'm not interested in using these tools at this time. - 200 identical rack mounted machines need to be upgraded from RH7.3 to SuSE9.2. - Each have 2 SCSI disks in them. the second drive is not in use or formatted for that matter. - One machine had Suse manually installed on it and configured for our network. (autofs,nis et. al) - this machines HD was imaged using DD and copied to a remote server. - DHCP was set up on this machine, the DHCP server has all 200 machines MAC to IP mappings, they always pick up the same information. - DD'n the image file back to the second HD over the network to one of the nodes works great. The machine boots and is mostly happy except it can not configure the interface as the config files are looking for the interface with the "masters" MAC address. this is the machine specific file I speak of: -rw-r--r-- 1 root root 133 Mar 30 09:46 ifcfg-eth-id-00:07:e9:21:f6:f0 my question: Can I configure SuSE in a way which it will configure the interface with the DHCP server supplied information without first 'setting the interface up via one of the built in tools (yast) or manualy editing a file? Similar to how RH handles it. With the RH systems I set the master image to use DHCP and all the cloned machines worked as expected. basically what i'm after is all these machines (created from the same unmodified image) booting and grabbing an IP from the DHCP server without any interactive-ness on our end. Is this do-able on SuSE without the use of tools simular to xcat? thanks people, and sorry for the long email.. greg

I do believe you can still use ifcfg-eth0, ifcfg-eth1 instead of the mac address. Brad Dameron SeaTab Software www.seatab.com
thats great news Brad, I'll give it a go, thanks much! greg Brad Dameron writes:

Brad, a simple rename of the file did it. thank you. greg Greg Whynott writes:
